PLSSSSS HELP!!!!!!!!!

Mathematics
1 answer:
Anna11 [10]3 years ago
6 0

Answer:

x=30º

∠CAB=60°

∠ACB=80°

Step-by-step explanation:

Because the angles of every triangle add up to 180º, we know that:

2x+20+2x=180-40\\ 4x=180-40-20\\ 4x=180-60\\ 4x=120\\ x=\frac{120}{4}

x=30º

Plug that in for x on both angles, and you will get

∠CAB=60°

∠ACB=80°
